Abstract (en)

The present invention provides a method of manufacturing a honeycomb body (1) formed by winding a flat metal foil (3) and a corrugated metal foil (4) in layers and brazing them, capable of reducing the equipment cost of honeycomb body manufacturing facilities and conforming to the countermeasure against an engine misfire problem of the honeycomb body, without causing insufficient or excessive application of adhesive which is seen in the cases of adhesive application methods using rolls; and relates to a method of manufacturing a honeycomb body characterized by: applying an adhesive to the portions to be brazed of the flat or corrugated foil corresponding to a bonding portion (17) which is located at one or both ends of the honeycomb body and/or a bonding portion (18) inside the honeycomb body over a cross section which is located away from one or both ends thereof in the axial direction; then, winding the flat and corrugated foils in layers to form a honeycomb body; then, making the portion of one or both end faces of the honeycomb body corresponding to the bonding portion (16) over the full axial length of the honeycomb body outer layers contact the surface of a liquid binder and having the binder sucked up along contact lines (5) of the flat and corrugated foils; and, then, feeding a brazing filler metal in powder to the honeycomb body so as to have it deposited at the portions where the adhesive and binder have been deposited. <IMAGE>
